os: wrap recvmsg(MSG_CMSG_CLOEXEC)

Browse source 
Some system C libraries do not have MSG_CMSG_CLOEXEC. This flag would
automatically set O_CLOEXEC flag on any received file descriptors.

Provide a fallback that does it manually. If setting CLOEXEC fails, the
file descriptor is closed immediately, which will lead to failures but
avoid leaks. However, setting CLOEXEC is not really expected to fail
occasionally.

Add tests for the wrapper. The setup is copied from connection-test.c.
